Original Song: The Persuaders "Thin Line Between Love and Hate" (1971)

Say what you want about the melisma-and-cumshot-addicted R&B acts of the '90s and beyond, but most have had sense enough not to highlight their incompetence by attempting to revive soul classics of an earlier, more tasteful era: Amazingly, Jodeci never covered the Stylistics, and Chris Brown does not seem to have recorded any Al Green songs yet.

Boot-knockin', lick-u-uppin' Houston trio H-Town were the exception, though, and they sound like they're in pain. Which sort of makes sense given the verse where their jealous wifey lands them “in the hospital, bandaged from feet to head” for getting home at 5 a.m. But it's doubtful that was their intention.
